Answer:

1126.4

Step-by-step explanation:

5.97 x 1024 =6113.28

4.87 x 1024= 4986.88

6113.28-4986.88 =1126.4

1+secA/sec A = sin^2 A / 1-cos A

Fofino [41]

Answer: see proof below

<u>Step-by-step explanation:</u>

$\dfrac{1+\sec A}{\sec A}=\dfrac{\sin^2 A}{1-\cos A}$

Use the following Identities:

sec Ф = 1/cos Ф

cos² Ф + sin² Ф = 1

<u>Proof LHS → RHS</u>

$\text{LHS:}\qquad \qquad \dfrac{1+\sec A}{\sec A}$

$\text{Identity:}\qquad \qquad \dfrac{1+\frac{1}{\cos A}}{\frac{1}{\cos A}}$

$\text{Simplify:}\qquad \qquad \dfrac{\frac{\cos A+1}{\cos A}}{\frac{1}{\cos A}}\\\\\\.\qquad \qquad \qquad =\dfrac{1+\cos A}{1}$

$\text{Multiply:}\qquad \qquad \dfrac{1+\cos A}{1}\cdot \bigg(\dfrac{1-\cos A}{1-\cos A}\bigg)\\\\\\.\qquad \qquad \qquad =\dfrac{1-\cos^2 A}{1-\cos A}$

$\text{Identity:}\qquad \qquad \dfrac{\sin^2 A}{1-\cos A}$

$\text{LHS = RHS:}\quad \dfrac{\sin^2 A}{1-\cos A}=\dfrac{\sin^2 A}{1-\cos A}\quad \checkmark$

16 POINTS HELP ASAP plzzzzzzzzz

Answer:

$\large\boxed{\large\boxed{\sqrt{3}$

Explanation:

You are comparing irrational numbers.

By inspection, i.e. at first sight you can only compare $\sqrt{3} \text{ }and\text{ } 2\sqrt{3}$ because they have the same radicand.

You can order: $\sqrt{3}$

You can introduce the 2 inside the radical by squaring it:

$2\sqrt{3}=\sqrt{2^2\times3}=\sqrt{12}$

Since 5 is between 3 and 12, you can order:

$\sqrt{3}$

Which is:

$\sqrt{3}$

You must know that π ≈ 3.14.

5 is less than 9 and the square root of 9 is 3; hence, $\sqrt{5}$ and $\sqrt{5}$

Now you must determine whether π is less than or greater than $\sqrt{12}$

Using a calculator or probing numbers between 3 and 4 you get $\sqrt{12} \approx3.46$

Hence, the complete order is:

$\sqrt{3}$

A survey team is trying to estimate the height of a mountain above a level plain. From one point on the plain, they observe that

aliya0001 [1]

Answer:

5507.79 feet

Step-by-step explanation:

To find the height of the mountain, we can draw triangles as in the image attached.

Let's call the height of the mountain 'h', and the distance from the first point (31 degrees) to the mountain 'x'.

Then, we can use the tangent relation of the angles:

tan(34) = h/x

tan(31) = h/(x+1000)

tan(31) is equal to 0.6009, and tan(34) is equal to 0.6745, so:

h/x = 0.6745 -> x = h/0.6745

using this value of x in the second equation:

h/(x+1000) = 0.6009

h/(h/0.6745 + 1000) = 0.6009

h = 0.6009 * (h/0.6745 + 1000)

h = 0.8909*h + 600.9

0.1091h = 600.9

h = 600.9 / 0.1091 = 5507.79 feet
